tisanes To all i/f/wm. t may concern: -r eA it known that I, @Lyon W.CLEVELAND, a. citizen-ol`v the United States, residing at Louisiana, -inthe county of Pike arid'btate oi Missouri, have invented certain new anduseful Improvements in` Dust-Caps .for

Values, of which .the following is a specification. '*This inventionrelates to an improved diisticap-lor-a 'val-ve such as is used inconnectioirivith aiiintlated autoii'iobile or b-l cycle tire and theprincipal object ofthe invention is to provide a cap which is soconstructed `that it will be easy to secure or rel vlase the same. v

. Another object of the invention is to pro- .vide an improved type oflocking' nut for engaging the fianfre ot the cap to releasalilyylioldthe cap in a secured position. n

.Another object of the invention is to s construct the lockingr nutthat'it may be readily". turned by hand or bymeans of a wrench and: toso construct the nut that `when in .place vthe nut will ,be locked andthus prevent it iroin accidentally moving to a releasing position.

Another object yoit' thein'ventioii is to'so constructthis dustcap andsecuring nut.

thatth'ey may lbe. used .in connectiony with 30 yvalves ot' thesti'uulardvtype whichare" already upon the market.y

This invention is illustrated iii the accompaiiynig: drawings.fvvhereiiiz" Figure' l is a vieu" showing the improved `dust cap andsecuring" nut mountedl Vupon n. vconvontioiial, t \,'pe. of valvehousing, thev dust cap and nut heine,r shown in section and the valveheilig' shown in'elevation.

ingas shown in Fig. l andisprovided with l `a reduced neck '17 whichisprovided with oppostiely disposed flattened sides118 whichsidesfengage thefiattened `sides l1'1 of 'the valve housing as shown finFig. 2 and thus prevent the dust cap 'fromrotating upon the,valveihousing Thisnecli :17 'terminates in aV rcollar k19, whichkcollar lis provided with radialextendingteeth as vshown` in Figs. 2 andl the purpose of `\\`="l'iieh Awill he hereinafter 'brought out. "Uponali-inspection of Figs. 3 and l it will also be notedthat the `collari-s provided with a cutout or notch 20 which notch permits' a tooth' 21to passV dust cap is through the colla-r `when the put in place. v

After the, dust ca-p Ilias yheen Vput in place upon the valve housing itis desired to lock the lsaine in place to `preventit from becoming' lost`and therefore the nut 22 has Ibeen provided. v rlhis nut 22' `is:provided Yivith a milled outer face so' that it may be j engaged by awrench if desired and is also provided with `a finger or-ear so that thenut may `be turned with `the fingers' instead lot withia wrench. rlhecentral `passage '2l of the nut is threaded'z'is shown in Fig. 5 so thattheiiut .may be turned upon the commonly used valve housing and held,inan adjusted positioiuthe end portions of the central passage being'enlarged to form the seats 25 and :26.v The seat 25 is of sullicient'sizeto receive the collar 19 of the dust cap "and the tooth 2l extendsfrom the wall of the Vseat at a sul'licient distance troni thel iiii'ierwall ot' the seat to permit the collar to pass between the tooth andtheinner wall of the seat when the nut is turned to the position'shown inFig. 2. Frein an init will khe readily Seen that when the nutis'turn'edlto this'position the tooth '.1 will engage the collar 19 andthus prevent aiiv danger oic the dust cap slippingpoll' of the valvehousing. It will he Jfurther noted from an inspection oic'tliis ligurethat the radialtceth of the collar will forni locking: nicaiis toprevent the aec-i' dental releasing oi" the. nut. this heine' due to thefact that \vhe.i the. nut is turned to a locking' position the tooth isbrought into tight engagement with the collar and thus tend to draw thedust cap toward the inner end of the valve housing. The. seat 25 isprovided so that a washer or gasket 27 can be placed about the valvehousingr and engage the fell)1 of a wheel when the nut 22 is tightened.

lVhen in use the dust cap is in place as shown in Figs. l and E?. withthe tooth 2l `engaging the collar 19 to securely hohl the dust cap inplace. When it is desired to inllate the tire the securing nut is turnedto bring the tooth into position to permit it to pass through the notch2t) and the cap can then be drawn troni the valve housing. The cap 12 isnow removed and the tire inflated and the eap 12 is then replaced andthe dust cap 1G put in place. After the dust cap is in place and thetooth 2l has passed through the notch Q0 the nut is returned to the position shown in l-ig. 2 thus securely locking the dust cap in place andpreventing any danger of its hecoining lost.

I claim:

1. A valve. housing, a cap for said valve housing, a dust cap ittingupon said valve housing and secured against rotation thereon and alocking nut threaded upon said valve housing and provided with a seatinits outer face, a collar extending from the inner end of said dust capand fitting within said seat and provided with a cutout, and a securingfinger extending.,r from said nut and across said seat in spacedrelation to the inner wall thereof, said finger passing through thecutout ot said collar when said collar is iuoved into said seat and saidlinger engaging the outer tace olj said collar when said nut is turnedto a locked position. V

2. A valve housing, a locking nut threaded upon said valve housing, alinger, a dust cap iuelosing the outer end portion ot' said valvehousing and statured against rotation thereon, and a collar extending'trein said dust cap and provided with a cutout through which saidlinger passes when said dust cap is placed upon the valve housing, saidfinger engaging said voila;- u'hen said nut is turned to a lockingposit-ion to clamp said collar between said finger and the outer face ofsaid nut.

3. A valve housing having flattened sides, a securing nut threaded uponsaid housing, a finger for said nut, a dust cap incl'osing said valvehousing and provided with a reduced neck having flattened sides engagingthe tlattened faces of said valve housing to permit no rotation of saiddust cap upon said valve housing, and a collar extending from said neckand engaging said nut and provided with a cut out through which saidlinger passes whereby said linger may engage the outer face ot' saidcollar when said nut is turned to a locking position and clamp saidcollar against the outer face of said nut.

4. A dust cap provided with a reduced neck shaped to conform to avalvehousing in cross section to prevent rotation of said cap upon saidhousing, a collar extending ironi said neck and provided with a cutout,and a securing nut provided with a seat to receive said collar and witha finger passing through the cutout of said collar and engaging theouter face thereof to hold said collar in said seat when said nut isturned to a locking position.

5, A valve housing, a locking nut screwe upon said valve housing, saidvalve housing having one side flattened, a dust cap fittin;r upon saidvalve housing and having one portion reduced to conform to the eontourof said valve housing in cross section, a collar extending t'roin saiddust eap and provided with a cutout, said locking nut heing providedwith a depression forniing a pocket to receive the collar ot' said dustcap, and a finger extending from the wall of said pocket toward thecenter thereof, the pin passing. through the cutout of said collar andsaid collar. being then turned to iuove beneath the pin.
